Just found this a couple of days ago and it has inspired me and given me some ideas for projects. Awesome job.
A couple of ideas for you. I'm only about halfway through, so these items might have been covered. For the headliner, have you considered trying to mold something out of Kydex? I don't know if you could get a big enough sheet for the headliner, but I think if you used a heat gun you could form it into whaterver you wanted. Probably would have been easier with the cab off, you could turn it upside down to work with it. Second on the brake booster. I saw you had clearance issues with your shift linkage, is there a reason you didn't go with hydroboost?

I would like to have some more information on this, do you rent it out? Where is it....i want to go! LOL

Sorry I don't get on here often anymore and missed your question, our rental is in the Turks & Caicos Islands and runs about $2500 for the week. - Pretty affordable for a house in the Caribbean directly on the beach. BeachsideBungalow is the name of our house and website, just google it for more info.
